6 Claims.

This invention relates to a sprinkler designed and adapted for sprinkling lawns, gardens, golf courses, etc.

One of the objects of the invention is to provide a sprinkler of the indicated character having sprinkler means which oscillates so as to sprinkle a relatively large or small approximately square or long rectangular area of a lawn, garden, sloping lawn. side of a hill and an embankment.

Another object of the invention is to provide an oscillating sprinkler with means whereby the speed of oscillation of the sprinkler may be varied without variation of water pressure or volume at sprinkler head.

Another object of the invention is to provide a sprinkler of the indicated character with means whereby the sprinkling means may oscillate or be held stationary in different positions in relation to the base on which the sprinkler rests, to the end that, the sprinkler may be used advantageously for sprinkling narrow lawn areas and hedges.

A further object ofthe invention is to provide an oscillating sprinkler which will operate under low water pressure and which is economical and simple in character, and which is compact and light for convenience of handling and transportation.

With the foregoing and other objects in view, the invention resides in the provision, combinations and the operation of the parts hereinafter fully described and illustrated in the accompanying drawings, in which:

Figure 1 is a side view of a sprinkler embodying the features of the invention;

Figure 2 is an end View, the sprinkler head being shown oscillated in dotted lines;

Figure 3 is an enlarged vertical transverse section on the line 3-3 of Figure 1;

Figure 4 is an enlarged horizontal section on the line 4 4 of Figure 1;

Figure 5 is an enlarged section on the line 5 5 of Figure 1;` y

Figure 6 is a detailed section;

Figurel 7 is an enlarged horizontal section on .the line 7-7 of Figure 1.

Referring now more particularly to the drawings it will be apparent that the sprinkler includes a substantially U-shaped casing 10 of sectional construction having depending water inlets l11 and 12, and upsanding outlets 13 and 14. The inlets 11 and 12 merge and communicate with a passage l5 within a horizontal portion of the casing l0 extending between the outlets 13 and 14. and which passage 15 communicates with the outles 13 and 14. The casing 10 also has a recess or chamber 16 which communicates at one side with the passage 15 intermediate thereof. A sprinkler assembly is mounted for oscillation in 1932. Serial No. 589,731

(Cl. 299-67) Y which fittings alsoy connect with the bushings 21 respectively. The opposite ends of the tube 20 aie respectively connected with the fittings 23. The provision and arrangement is such that .the

sprinkler head 17 may be oscillated, and also may have water delivered thereto from the outlets 13 and 14. It will be apparent that the outlets 13 and 14 serve as conduits for the water, and also a means to 'support the sprinkler assembly.

Means is provided which operates in response to the force of the water as it ows through the casing 10 to the sprinkler 'head 17 to cause the oscillation of the sprinkler assembly. The said means includes a water wheel 24 of any practical type which is arranged in the recess 16. The

blades 25 of the wheel 24 project into the passage ,15 to be acted on by the water. The wheel 24 is fast on a shaft 26 which is supported for rotation by the parts of the casing 10. An arm 27 is secured to the upper end ofthe shaft 26 by a set screw 28 so that the arm will rotate with the Wheel 24. One endof the arm 27 has a slot or guideway 29 which slidably receives therein a grooved block 30, the grooves in the block being .at opposite sides to respectively receive the sides of the guideway 29. A pin 31 projects upwardly from the block 30. An antifriction sleeve 32 is arranged on the pin 31 and is freely rotatable thereon. The sleeve 32 is held in place by a head 33 detachably connected with the pin 31. An adjusting screw 34 is in threading engagement with the arm and the block 30 for the purpose of chanaging the position of the pin 31 inrelation to the axis of the water wheel for a purpose to appear hereinafter. A rocker35 in the form of a slotted element consists of side members 36 and trunnions 37 which are connected with the lside members 36. The trunnions 37 are in axial alinement with each other. and are respectively received in holes in bearings 38 which are rev has connected therein aregulating valve 39 of Y any suitable type for a purpose to appear.

The sprinkler includes a base 40 which is in the form of a sled because it has runners 41 which makes it possible to draw the sprinkler along the surface of the ground. The base is connected with the. casing/.10` so that the. casing 10and the sprinklerassembly carried thereby 'rwill be adjustable in relation to the base 40. The said means consists of two parts, a part 42integral with the base 40 and a part 43. The parts .42 and 43 have their inner faces serrated radially as at 44 and are held clamped together by a clamping bolt 45 and nut 46. The part 43 has an arbor 47 which is received in a bore 48 in'an enlargement on the under side of "the casing 10. The arbor 47 has a circular groove 49. A set screw 50 is threaded in said enlargement and the inner end thereof projects into the groove 49. It will beapparent that'the casing 210 is adjustable on a horizontal axis, whichis the bolt 45, and also on a vertical axis .which is the arbor 47. By loosening the nut 46 on the bolt 45, the casing 10 may be movedto different positions in a vertical plane. By loosening the set screw 50 the casing maybe adjusted in a horizontal plane to any desired position in relation to the base. From the foregoing it will be understood that one or both of the inlets'll and 12 may be connected .with a suitable supply of water under pressure which may be conveyed thereto from said source by a hoseor pipe connection or connections with suitable coupling means on the inlets. The water ows to the passage 15 impinging'itself against the blades 25, thereby operating the .wheel 24. 'Ihe water flows to the outlet '13, through openings in the bushings 21, thence to the tubes 18 and 19 at the left, thence to the tube 17 to the tubes 18 and 19 at the right to the oulet 14 and is stopped by the valve 39 which will be closed. Pressure will force the water out through the multiplicity of holes in the head or tube 17. As the wheel 24 rotates by the force of the water, the .arm 27 will rotate with the wheel,.and.as a consequence the pin'31 will act on the side members 36of the rocker 35 causing the sprinkler assembly 'including the head or tube 17 to oscillate. In this manner a lrelatively large area may be sprinkled. By manipulating the valve `39 the volume and pressure of water operating on the wheel 24 may be altered, to reduce or increase .the speed of oscillation of the sprinkler head without changing the volume or .pressure of water at the sprinkler head. By manipulating the screw 34, the position of the ,pin 31 in relation to the axis of the wheel 24'may be changed in order to vary the degree of osciljlation of the sprinkler head so that a relatively largeor small area Vmay be sprinkled at will.

The sprinkler may be used advantageously for sprinkling sloping lawns, the sides of hills and embankments, by adjusting the casing 10 in relation to the base 40. This as stated hereinbefore is accomplished by loosening the nut 46 and adjusting the part 43 with respect to the part 42. "By so adjusting the Acasing 1o in relation to the base the latter may rest on the sloping lawn, etc. as the case may be and the sprinkler and head 17 will be disposed substantially parallel to the surface of ,the area to be sprinkled.

In accordance with another feature of the invention the water wheel 24 may be prevented from rotating and the sprinkler head held stationary for sprinkling narrow areas of lawn or the like and hedges. The said means consists of a toothed wheel 51 integral with the arm 27, and a screw stop 52 adjustable in a .block 53 on the .casing l0. The stop 52 may .be engaged between any pair of the teeth of the wheel 51 to hold the sprinkler head 17 at any angle within the range of` movement thereof. The stop is held against movement .by a Vset screw 54 carried by the block 53.

The inlet l2 may be closed by a cap`55 when 80 This cap 55 is held captive handle of the valve 39. The runners 41 of the 85 base Vhave holes v57 in the front ends to receive arope or-the like-for drawing the sprinkler over the ground. The ends of the head or tube 17 'may Ybe provided with nozzles 58.

VA suitable .bushing and packing 60 around the 90 shaft'26 between the casing 10 andgear 51" prevents leakage at this point.

By means of one or .the other .of the inlets 11 or 12 two or more sprinklers'may be connected in series by the use of hose "or rigid pipeline.
